Small scale reflow oven

Electronics Forum | Wed Apr 10 22:15:58 EDT 2019 | kylehunter

So after listening to many people's options and thoughts, I have decided against novastar. There is a reseller near my office that offers full support, training, and service on used equipment. They also fully refurbish all equipment beforehand. I no

Conveyor belt moves opposite direction

Electronics Forum | Tue Apr 23 06:26:18 EDT 2019 | jfeustel

Kanetic did implement a feature into their PLC code that would allow for simple reversal of the board flow. This is why the conveyor suddenly reversed direction after so many years. Because the feature was invoked by holding down a button it was kno

Squeegee Blade selection OEM? Coated?

Electronics Forum | Wed May 08 18:04:02 EDT 2019 | slthomas

You would have to do some extensive testing to really now for sure how much better coated blades perform than OEM blades. Deciding whether or not they last longer is just a function of regular inspections under a scope and accounting for the number

Load Cell Temperature

Electronics Forum | Sat Jun 29 04:11:31 EDT 2019 | jackson_jade4

Well, I know that this is not directly related to the pycom device, but the code and load cell are connected to the device so I am hoping to gain from the wealth of knowledge and experience on this forum. Until a few weeks ago, I knew nothing at all

Rad 5 performance: bent lead

Electronics Forum | Mon Jul 08 12:21:17 EDT 2019 | slthomas

I forget which type of CTA that machine has so I probably won't be much help. It's been ages since I worked on them but it doesn't look like you'll find many people that have. That said, usually if you get things aligned properly and it still bends

Ekra E5 question

Electronics Forum | Mon Mar 23 15:08:21 EDT 2020 | slthomas

Unfortunately I didn't do the work...I just requested it from maintenance. I think the E5's were really a completely different beast than an E4, but I've never used an E4 so really don't have any experience. I purchased 3 E5's when new for a previou

Solderless Methods for Tuning RF Circuits

Electronics Forum | Fri Oct 25 13:23:02 EDT 2019 | SMTA-Joe

Hello SMTA, This may be beyond the scope of the SMTA since it does not strictly deal with assembly of electronics, rather, it is about potential solderless methods for manually tuning RF circuits. Our Engineers & QC have tasked manufacturing with

LED lifted soldering defect

Electronics Forum | Wed Dec 04 04:28:58 EST 2019 | oxygensmd

It seems there isn't right connection between solder and solder-legs. Maybe check that the LEDs get huminidity, have some oxidation on the legs, try different solder paste, check the reflow solder profile. On the photo I can not saw properly reflowe

LED lifted soldering defect

Electronics Forum | Wed Dec 04 08:00:57 EST 2019 | kylehunter

Thank you both. We are using EP256 Solder Paste Sn63Pb37 no clean from Kester. I attached our profile as well as Kester's target profile. We used a populated demo board for the profile. We tested along the width, and was less than a 2c difference.
